How do you change the font color of text in a Word document table using Visual Studio 2010?

I'm trying to figure out how to change the font color of text in a Word document table using Visual Basic, but I can't seem to figure out the correct syntax. This is what I currently have in my code:

Dim rngCell As Word.Range
rngCell = tbl.Cell(1, 1).Range
tbl.Cell(1, 1).Range.Text = "1.  ACCOUNT CREATION"
tbl.Cell(1, 1).Range.Font.Size = 18
tbl.Cell(1, 1).Range.Font.Bold = vbYes
tbl.Cell(1, 1).Range.Font.ColorIndex = wdBlack

The last line of code containing "wdBlack" has a syntax error.  Does anyone know what the correct syntax should be in order to change the color of the text in this table cell to black? 

Thanks in advance,

Jim
